Hi , just looking for some opinions/advice on the Xenarc 800TSV

I am just deliberating between the XENARC 800TSV and 700TSV.
However I am put off the 800TSV due to the native
resolution of only 640 x 480, how does this display look
when it`s in 800x600? can you tell its not the native resolution?
is the screen still crystal clear, and so on :-)
